quiet mufflers and gains of a h-pipe

[btchncamaro]

right now i have two chamber flowmasters. the car sounds awsome, but is really loud. i am looking for quit, but flows well. i was thinking about the cone inserts that go into the collector, but for 45-70 bucks why not spend the little extra, (if i had too) and get new mufflers. also i dont have a h-pipe and was wondering if it was worth adding. i have hooker supercomp headers (1"3/4) to 3" exhuast straight off the collector to the flows, then up over the rear and dumped behind the tire.

they say you gain about 5 lb-ft with an h-pipe, my buddy put one on his mustang, huge cam and blower, and it seemed to take a lot of the rasp out of it. I would say put the H or X pipe on and see how you like it. If you still wanna change all you have to do is get different mufflers.

but what is a good hi flow quiet muffler??/

[btchncamaro]

suprise people when they get smoked! right now the car sound a little to racey (not to be confused with ricey). its really loud and since i drive it on the street as much as i do, i rather go for the silent but deadly thing (not to be confused with a fart)

I have a Jegs 2-1/2" exhaust kit on my big block car and its really got a nice sound to it the mufflers are turbo type but I don't know who made them for Jegs, but I think they are available seperately and my car has good power even with the full exhaust .

We had flowmaster delta force race mufflers( single chamber) on our 67 camaro, it was running 12.10-11.99. When we changed to the dynomax race magnums the car ran 11.80 -11.70's. Dynomax magnums run about 37. each, and they are a little bit quiter than flowmaster's.

thanks for the input guys, how about an "x" or "h" pipe. i am not really looking to replace my whole exhuast if i dont have too, but i see 3" kits fairly reasonable or just a h-pipe kit by itself for 30 some bucks or so. 30 bucks sounds pretty good.

Just so you guys know We at Rons Race Shop sell a muffler called Spintech. I think some of you have heard the name Well They flow much better than the Flowmaster mufflers and they're more quiet than Brand F.
They have many different styles of mufflers but I use the Sportsmans on my camaro and they sound good much better than Brand F

Don't get me wrong now I'm a huge Flowmaster fan and have them all my cars except the Camaro and for the price I think they are worth every cent

Now I would also use the X-pipe over the H-pipe only because of the scavenging the x-pipe has over the H-pipe building more in the bottom to mid range power that you need more on a daily driver.

I have an H-pipe now and never noticed any differance with or with out it.
but I have heard so many better things about the x-pipe.

just a few thoughts for you

[mike mitchell]

being that you already have a 3'' exhaust limits you on the desible rating.are you running a big block? if not, this exhaust is going to ruin your low end tourqe. if you dont have a built motor (450 or more hp ) you over shot the exhaust. this is just my oppinion. so, you should at least go with the X pipe to lower the sound. the only way to get you in the sleeper positin is to put differant mufflers on. you may compromise alitte power. but, it will be better on your ear drums...and not let the compotion know what you have....

[mike mitchell]

had to add this last opinion. if your running a small block, running the smaller 1 5/8 headers will help you on your torque for the street. everybody wants to have the system that sounds knarley. but your going to have to compromise something to get that sound.

[btchncamaro]

i think my headers are hooker super comps, 1 3/4's i believe, i honestly forget. last year with my 406, i had 200 cc iron eagle heads 11-1 compression i made 393 hp/ 515 ft lbs tq. this year i upped to 12-1 and dart pro 1's 215's that have had some port work done so i am guessing i should be making right about 450 hp all motor if not a little more, plus the extra 200 shot wakes it up a little more. i think i am going to go with the dynomax ultraflows (i think that what my buddy said, his car sounded good)when i get around to it, as of now i have some bigger issues to deal with. thanks for the input all, and will probably be getting a x pipe also.

[mike mitchell]

not only will the x help on the sound. it will create alittle bit of torque too.

look into the moroso spiral flow bullet mufflers.. i remember listenning to a clip of them when i was buying my dual exhaust parts and i didn't get them because it was too quiet for what i wanted.

its still pretty loud and nice sounding, but probably quieter than what you have on right now..

also if you have the money, borla's are pretty mellow at lower rpms, but when you open it up they will roar.

The American Thunder setup, comes with 40 series mufflers. Flowmaster makes a quieter version, the 50 series that has as good or better flow than the 40's. I haven't heard them, but I'm planning on using them on my '68.
